Setting a single row as HTML colspan

I am new to AW but am looking to purchase AW mostly for the grid. Before I do, I need to verify that two features we need can be done in the AW grid. I will describe one needed feature here and start up a new topic for the other.

I need the ability to have an entire row in the body of the grid to be set up using the HTML colspan feature or similar to the merge cells option in Excel. I would like an entire row to be set up as a single cell (with possible text in the cell.

I have seen a few topics using colspan in the grid header but not much about how to set it up in the body of the grid.
